Part digital clock with switch presetting Circuit Block Diagram and Description sw111-8) swU15-121 sw[7-4] sw[17] preset h1 ho m m0 50MHz 1Hz counter freq divider (mod 60) hour Sec min 7-seg 7-seg 7-seg 7-seg 7-seg 7-seg Fig.1 the diagram of digital clock The digital clock can display the hours (00 to 23), minutes (00 to 59) and seconds (00 to 59) at the same time using six (6) 7-segment displays. The initial time can be preset by switches as follows: when SWI170 1 (time setting mode), SWI15-0) will preset a 4-digit BCD number for initial hours and minutes, initial second is always 00; when SWI17) 0 (clock running mode), the digital clock will work nomally starting with the preset hours and minutes and 0 second.
